Chainfire’s Holey Light app for showing notifications on the Samsung Galaxy S10’s hole punch gets updated to support the Always on Display

Chainfire‘s Holey Light app quickly catapulted into becoming a fan favorite, as users of the Samsung Galaxy S10 flagship lineup flocked in droves to turn the area around the hole punch display into a replacement for the missing notification LED functionality. The app had a few shortcomings at the time of its release, but XDA Senior Recognized Developer Chainfire is not known to shy away from challenges. As such, the app has received updates that now allow it to support the Always On Display on the Samsung flagships, as well as reduce the CPU and battery usage by the app.

The developer has listed out some of the significant recent changes as below:

  • Screen off + battery functionality enabled
  • Migration from fake lockscreen to AOD-base
  • Migration from application to accessibility overlay (Google frowns on this, though)
  • Any notification can now be used for LED. The ones that don’t ask for LED show up under Colors as black by default
  • Lottie renderer has been replaced by a sprite-sheet based rendered (up to 5x CPU reduction)
  • Battery saving animations added (up to 3x CPU reduction), blinking and pie-chart (decided based on full or on-tap AOD)
  • Several leaks and crashes have been fixed (and undoubtedly new ones created)
